FS25 Moisture System V2.0.0.8
This mod adds moisture simulation and crop quality tracking to Farming Simulator 25. Moisture levels vary according to terrain elevation, weather patterns, temperature fluctuations, and day/night cycles, while crop quality affects selling prices and changes during storage.
Each harvested load receives a quality rating (0-100) based on its moisture content at harvest. Quality degrades over time when crops are stored above their ideal moisture level. Wet crops incur drying charges and reduced prices, while silo drying can reduce moisture and halt quality loss. Quality tables, price grades, and seasonal moisture projections are available through the in-game menu (Shift+M).
Features
- Regional weather simulation: choose a weather profile matching your region, with realistic seasonal patterns and yearly variation that directly impacts harvest timing and requires forward planning. See the guide on GitHub to create your own.
- Terrain-aware field moisture simulation driven by the active weather profile, with monthly variation patterns that reflect real regional climates.
- Crop quality system: quality is set at harvest, degrades hourly when stored above ideal moisture, and drives the selling price through crop-specific grade bands.
- Silo drying: walk up to any silo and activate drying to reduce moisture over time. Costs scale with volume and are cheaper than selling wet.
- Drying charges at the point of sale for crops above ideal moisture, shown as a separate finance entry.
- Grass management system featuring progressive tedding mechanics, weather-responsive drying rates, and automatic hay conversion at optimal moisture thresholds. Multiple tedding passes accelerate drying.
- Ground rot: grass and straw piles left exposed accumulate rain exposure over time, triggering progressive volume loss as organic material deteriorates. Hay reverts to grass if it gets too wet.
- Bale rotting: unprotected bales track cumulative rain exposure with initial tolerance periods, escalating decay rates based on exposure history, and limited recovery during dry spells. Wrapping and shelter infrastructure protect bales.
- Purchase the moisture meter hand tool in the store for precise field and pile readings on demand. You can display this in the HUD if preferred.
- Customization options for moisture dynamics, quality decay rates, drying speed, tedding efficiency, and decay parameters.
The mod is not compatible with the following mods: NonStopCrop, RealisticWeather.

2.0.0.8
- Hay conversion threshold, the moisture level below which grass becomes hay, is now a setting, with options 4/6/8/10/12%. Defaults to 8%.
- Improved how minimum and maximum weather profile temperatures are applied throughout the day.
- Fixed an issue with moisture not tracking correctly when using Silo Extensions.
2.0.0.5
- Added support for the Bulk Hall silos added in Highlands Fishing DLC. Moisture and quality will now be tracked for crops stored in these silos, and crops can be dried as normal.
- Fixed a multiplayer Lua issue when players join the server.
- Fields can now be irrigated by hiring contractors. Use the Moisture Menu to book jobs. Plan ahead to avoid higher prices for short notice and to ensure contractor availability. There are no visual effects for this.
- Moisture level now moves slightly more quickly both up and down. The goal is to more reliably produce intended outcomes in weather scenarios.
- The threshold for hay is now 10%.
- The default tedding moisture reduction is now 4%, and players can adjust this to be between 4-8%.
- Updated save game hook to reduce mod conflicts.
- Updated help texts to properly reflect the new grain drying approach.
2.0.0.3
- Tuned some weather profiles to properly account for how weather such as thunder impacts moisture.
- Grain drying is now started within the Moisture Menu (
Shift + M) rather than by pressing a key when near the silo. This avoids some issues with some silos while providing more information. - Durations of weather spells are now scaled based on the number of days per month. This helps with planning field work around weather introduced in v2.
- The moisture impact charts can now be hovered with the mouse to show specific yield and quality values for a given moisture level.
- The moisture system now controls weather. Choose a Weather Profile that matches your region in game settings. Many maps have appropriate defaults configured within the mod. Weather includes variability that simulates realistic seasonal patterns. This impacts your harvest and requires more planning than before.
- Moisture now impacts yield as well as quality. Crop that is too dry will generally yield badly, while crop that is too wet will generally yield well but with poor quality.
- You can write your own weather profiles. Visit GitHub and follow the guide.
- The moisture calendar has been replaced with a Weather information view, showing seasonal forecasts and historical weather data.
- The moisture to quality UI has been replaced with Moisture Impact. This shows the impact of moisture on yield and quality for a given crop.
- Generally eased material rotting, both for bales and ground piles. Material will take longer to begin to rot and will rot more slowly.
- Fixed an issue with grain drying not starting in multiplayer games.
- Vehicles and silos containing crops will now show the current grade of the crop in the HUD. Previously, only moisture and quality were shown.
- Added optimisations to how weather impacts ground piles to improve performance for lower-end machines.
- The impact of weather is now scaled based on the number of days per month.
- Drying charges are no longer applied when depositing into your own selling station.
- Existing crops that pre-date the moisture mod will now be assigned 100% quality and ideal moisture when first interacted with.
- Tightened the rate of crop drying so large volumes of crop do not take forever to dry.
1.0.0.7
- Fixed a freeze when selling certain silos.
- Improved the area detection for when the drying option will be offered.
1.0.0.6
- Miscellaneous optimisation to improve performance when a large number of ground objects persist.
1.0.0.5
- Harvested crop in a contract will be at the ideal moisture level to prevent drying costs being charged for contract work.
- Deregistered any sold silos to fix an error with crop drying.
- Added multiplayer fixes for issues introduced by the drying changes in 1.0.0.4.
1.0.0.4
- Introduced drying in silos. Crop price is now determined by quality, not moisture level as it was previously. Quality is initially determined by moisture level. Dry crops to avoid quality degradation over time. Selling crops with excess moisture incurs drying charges.
- Added support for MacDon pack. Previously, crops harvested with this equipment would not track moisture levels.
- Added assurance on moisture grid lookup.
- Added support for beans, buckwheat, and millet crops, thanks to merittu.
- Added Ukrainian translation, thanks to sava4903-coder.
- Added Turkish translation, thanks to Cyber-Syntax.
1.0.0.3
- Added a safety check to prevent errors when using SIM Dashboard and using a harvester.
1.0.0.2
- Reworked events in multiplayer to reduce network traffic and subsequent issues.
- Fixed an issue with rotting bales in object storages in multiplayer.
- Moisture and grade are now visible when harvesting on the fill HUD.
- Fixed a sporadic issue where crops would sell for a very low price.
- Fixed various other multiplayer issues.
- Added a safety check to avoid an issue loading a game when there is a bale in a baler.
- Added Czech translation, thanks to Kynuska.
- Added Polish translation, thanks to KITT3000.
